Their son Manuel is now seven weeks old, but they have yet to meet him.

"This is the worst nightmare. Imagine waiting for so long and then having to wait even longer, with no clear idea of when we could be allowed to travel," says José.

Ukraine, like many other countries, has closed its borders to international visitors in an effort to limit the spread of Covid-19, which has killed more 300,000 people worldwide. That has left dozens of babies born to Ukranian surrogates - and due to be collected by their intended parents from overseas - in limbo.

Argentina has also imposed a travel ban on all commercial flights until September as part of a strict coronavirus lockdown, making it impossible for the couple to plan a trip for the foreseeable future.'We need to be with him'

"The physical contact at this point is key, he needs to be with us and we need to be with him," says the new father.

Flavia and José started their surrogacy journey in December 2018 and travelled to Kyiv four months later to create their embryos out of his sperm and her eggs.

An embryo was then transferred into the womb of a gestational carrier, or "surrogate mother", that they had contacted through a local clinic.

"We never met our surrogate, the clinic managed the relationship and we don't really know much about the specifics. We do know that her fees were paid, of course," says José.

Commercial surrogacy is legal in Ukraine, and a big business too - though there have been concerns about the level of oversight of the industry, which has expanded significantly in recent years.

The cost of an average assisted reproduction package ranges from $30,000 to $50,000 (£25,000 to £41,000), a fraction of what it costs in the US and other countries where commercial surrogacy is permitted.

For the Argentine couple, it meant asking for a loan as well as borrowing money from family. They won't say how much they have spent but that "probably half of it went to the surrogate".

"When we got confirmation that the transfer had been successful in late July, we started planning every single detail. We wanted to travel days before the due date, which was 10 April," says Flavia. "In the meantime, we lived this pregnancy through the monthly scans the clinic was sending us," adds José.

From optimism to despair

The couple had booked transatlantic flights for 2 April, with a stopover in Madrid.

As the coronavirus outbreak started spreading and hit Spain badly, they realised their trip might not happened as planned.

"But at first we didn't think we wouldn't be able to travel at all. I think we had this false optimism, it was more like, 'uh, it may take us longer to get to Ukraine'. We kept on planning even as we watched airports starting to shut down everywhere," says Flavia.

As European countries closed their borders and Argentina went into lockdown in mid-March, the couple began to despair. "I was terrified. We knew circumstances were exceptional, but we underestimated the implications," says Flavia.

The picture got complicated further by the fact that both work in healthcare. Flavia is a social worker and José is a medical doctor in an intensive care unit at a hospital just outside Buenos Aires who has been treating Covid-19 patients.

As key workers, they were not allowed to take time off at first.

"We started communicating regularly with the Ukrainian clinic's Spanish-speaking coordinators via WhatsApp to come up with a plan," says José.

Stay put, was the message. The fertility centre had set up a place for Manuel to stay while he waited for his biological parents.

"They told us the newborn babies would be safe, taken care of, well fed… They calmed us down, at least as much as it was humanly possible," says José.'Our baby was born 12,500km away'

The couple's son was born early, on 30 March. The anxious parents were texted the news early in the morning as they were on their way to work.

"They told us we'd had a child, and we were 12,500km away… We had to stop the car, we almost had a crash," remembers Flavia.

Later that day they got to see their healthy, 8lbs-baby boy for the first time - through a photograph.

"Our surrogate asked the clinic if she could send us a WhatsApp message and she wrote to us to say she had a happy pregnancy, that she was proud to make our life-long dream come true," says José. "We never got the chance to meet her but we told her she completed our family and forever transformed our lives," adds Flavia.Baby hotel

The Ukrainian clinic made arrangements for the stranded surrogate babies to stay at a small hotel the company owns on the outskirts of Kyiv.

And it is not just Manuel, some 50 newborns are being looked after in a large dormitory-style nursery.

"All they are doing is looking after the baby's basic health and signs of a normal development," says José. "But nobody will be able to give him the love of a parent during these crucial first weeks. That is heart-breaking."

The number of babies being kept the hotel may keep growing if travel restrictions continue. New deliveries are scheduled over the coming weeks.

The hotel is normally offered as accommodation for the biological parents coming to Ukraine to collect their child. Now it is run by a team of nurses working round the clock under strict quarantine rules, says the fertility company.

A video circulated by BioTexCom just days ago, and published by media around the world, shows the number of babies born to surrogates which have not been able to be picked up due to the lockdown.

The images have also reignited the debate about what critics say is a loosely-controlled "baby-making business" in this Eastern European country.
